It will take 120 minutes to chop down 100 trees.
Bob chops 10 trees in 30 minutes, so he can chop 100 trees in 300 minutes.
Frank chops 15 trees in 30 minutes, so he can chop 100 trees in 200 minutes.
Solve this using the following equation:
15 / 30 = 100 / x
Solving for x gives 120 minutes.

Answer:
Dozen Oatmeal = $4 and Dozen Chocolate = $9
Step-by-step explanation:
Dozen Oatmeal:
10 dozen oatmeal and 1 dozen chocolate =$49
9 dozen oatmeal and 1 dozen chocolate = $45
The second customer bought 1 less dozen and paid $4 fewer dollars, therefore 1 dozen oatmeal must equal $4
Dozen Chocolate: let C = 1 dozen chocolate
10 dozen oatmeal + 1 dozen chocolate = $49
(10 x $4) + C = $49
$40 + C = $49
-40 -40
C = $9
1 dozen chocolate cookies = $9
Answer:
Question 3: 
Question 4: 
Step-by-step explanation:
<u>Question 3</u>
g(x) * h(x) means to multiply both the functions given.
Also note the distributive property:
Now, lets multiply:
The 2nd answer choice is right
<u>Question 4</u>
means to divide both the functions and simplify, if possible. Lets do this:
This is the correct answer.
The restriction on the domain is any x value that we CANNOT PUT IN THE FUNCTION.
We know we cannot divide by 0, so what makes this fraction division by 0??
If we put x = 0, the function is undefined. So x CANNOT be 0.
Third answer choice is right.
